tooth transplantation can be considered a valid and predictable treatment option for rehabilitating young patients with permanent teeth loss. this study presents several cases of successful autogenous tooth transplantation with a 6-9 months follow-up. tooth auto-transplantation can be considered a reasonable option for replacing missing teeth when a donor tooth is available. the auto-transplant...

AIM This was to assess the predictability of eruption of delayed permanent incisors after supernumerary removal and creation of adequate space, in relation to: root maturity, degree of vertical impaction, and degree of angulation of impaction. METHODS The dental records of children with supernumerary teeth delaying the eruption of permanent incisors were analysed. The type of a supernumerary ...

Orofacial trauma is a serious orodental and general health problem that may have medical, esthetic and psychological consequences for children and their parents. When the root of the primary tooth is close to the unerupted permanent tooth, primary tooth trauma may result in developmental disturbances and pulpal reaction in that permanent tooth. We report an unusual case in which injury to the p...

UNLABELLED The need for new dental tissue-replacement therapies is evident in recent reports which reveal startling statistics regarding the high incidence of tooth decay and tooth loss. Recent advances in the identification and characterization of dental stem cells, and in dental tissue-engineering strategies, suggest that bioengineering approaches may successfully be used to regenerate dental...

Introduction: Permanent first molar is the most important unit in the chewing system. Ear-ly loss of first molars can significantly reduce chewing efficiency, increase overbite, lead to premature eruption of the permanent second and third molars, and displacement of adjacent teeth. The purpose of this study was to determine the associated factors of permanent first molar caries in 7-9 years old...

Tooth formation begins with the bud stage during which the dental lamina (derived from epithelial tissue) produces a series of tooth buds along its buccal margin. This is followed by the cap stage in which a coned structure, termed the enamel organ, is formed by an invagination of mesenchymal tissue into the tooth bud. All deciduous teeth and permanent molars are derived from the enamel organ o...

Stem cell-based therapy has great potential in treating health conditions including cardiovascular, autoimmune, type I diabetes, neurodegenerative and bone and cartilage diseases also in spinal cord injuries, malformations and cancer. In addition to their potential use to treat systemic diseases, stem cell-based therapy also provides a powerful tool to treat oral and dental diseases such as cra...

In orthodontics, bone structure, its density and dimensions play an essential role by explaining limitations in magnitude, size and extent of tooth movement. Severe anterior crowding is one of the most frequently encountered dental malocclusions. Its therapy is mostly limited by lack of basal and alveolar bone and it often involves tooth extractions. Mandibular midline distraction osteogenesis ...

traumatic injuries in the primary dentition pose major challenges for management. this emergency treatment requires proper planning so as to achieve favorable results. trauma causing severe dentoalveolar injuries, especially in children, needs an interdisciplinary approach so as to retain normal functional anatomy for that age. this article describes a clinical innovative technique, which utili...

Several approaches are available to reduce pulsating torque components in permanent magnet motors. One of the known techniques is stator tooth shape modifications. This paper presents an integrated algorithm applicable for tooth shape optimization of permanent magnet motors. This method focuses on the reduced basis technique, finite element analysis and Taguchi method and is conducted on tooth ...
